How to Grow Coriander (Cilantro)

Step-by-Step Growing Guide:

• Location: Choose a sunny location that gets at least 4-5 hours of direct sunlight daily. Coriander grows best in temperate conditions but can also be grown indoors with a little care. If growing indoors, place it near a window with plenty of sunlight.
• Soil Preparation: Coriander prefers well-draining soil rich in organic matter. Loamy or sandy soil works best. Use well-draining, slightly acidic potting soil. A mix of garden soil, peat moss, and sand in equal parts is ideal.
• Sowing Seeds: Sow coriander seeds directly into the garden bed or container. Plant seeds 1/4 inch deep and space them about 6-8 inches apart. Soak the seeds in water for a few hours before sowing to improve germination. You can also prepare a seed starter mix at home by mixing soil with organic compost to enhance seedling growth.
• Watering: Keep the soil moist but not waterlogged. Water lightly every 2-3 days to avoid overwatering, as coriander doesn’t like soggy soil. To retain moisture and prevent the soil from drying out too quickly, you can add onion peels around the base of the plant. Onion peels release nutrients into the soil as they break down, acting as a natural fertilizer.
• Temperature and Humidity: Coriander grows best in cool weather (15°C to 25°C). Avoid placing it in too hot a location. Mist the plant with water during dry periods to keep the leaves fresh and encourage healthy growth.
• Harvesting: After 3-4 weeks, once the coriander leaves are mature and healthy, use scissors or garden shears to cut the outer leaves. Always leave the inner leaves intact to encourage further growth. You can also harvest seeds once the flowers bloom and the seed heads start turning brown.

Common Problems, Pests & Diseases

1. Leaf Curling: Caused by insufficient water or pest damage. Ensure consistent watering and check for pests like aphids. Spray neem oil 2 ml/20 drops or Mix 1 protec tab in 1 liter of water once a week for effective control.
   
2. Yellowing Leaves: Often due to overwatering, poor drainage, or nutrient deficiency. Make sure the soil drains well and consider adding compost. Spray seaweed extract 2ml/20 drops per liter water.
   
3. Aphid and Whiteflies: These tiny flying insects can damage the plant by sucking sap. Spray neem oil 2 ml/20 drops or Mix 1 protec tab in 1 liter of water once a week for effective control.
   
4. Fungal Diseases: Leaf spot can occur in overly damp conditions. Ensure good air circulation and proper drainage. Spray fungicides like Tricho Shield 5 gm/half spoon or Mix 1 protec tab in 1 liter of water per liter of water.
   
5. Coriander Root Rot: Often caused by overwatering or poorly draining soil. Avoid waterlogging and ensure proper drainage. To prevent or cure, mix 5 gm or half spoon of organic fungicide Tricho Shield per liter of water and drench 50 ml of the solution near the plant's stem. Repeat it 7 days after the first drenching for the best results.
   

Best Practices for Growing Coriander

1. Succession Planting: Plant coriander seeds every 2-3 weeks for a continuous supply of fresh leaves and to prevent bolting in hot weather.
2. Pruning and Harvesting: Prune regularly to encourage new growth. Remove flowers to prevent bolting and extend leaf harvest.
3. Mulching: Use organic mulch like dried grass or leaves to retain moisture, suppress weeds, and enrich the soil.
4. Soil Enrichment: Add organic compost every few weeks and bury banana peels and egg shells to boost nutrients like potassium and calcium.
